Nginx Issue with stream and upstream to VMware UAG

I'm trying to setup VMware UAG load balanced with Nginx. I keep getting this error,

nginx: [emerg] "stream" directive is not allowed here.

I'm not sure what I am doing wrong. I am in no way a developer so please excuse my ignorance. Thanks in advance Here's my config:

stream {
    upstream vdi_ssl {
        hash $remote_addr;
        server uag-01.example.com:443;
        server uag-02.example.com:443 down;
    }

    upstream vdi_pcoip {
        hash $remote_addr;
        server uag-01.example.com:4172;
        server uag-02.example.com:4172 down;
    }

    server {
        listen 10.4.44.2:443 ssl;

        ssl_certificate /etc/ssl/certs/*.pem;
        ssl_certificate_key /etc/ssl/private/*.pem;

        proxy_ssl_certificate_key /etc/ssl/private/*.pem;
        proxy_timeout 20m;

        health_check;
    }

    server {
        listen 10.4.44.2:4172;

        proxy_pass vdi_pcoip;
        proxy_timeout 20m;

        health_check port=443;
    }

    server {
        listen 10.4.44.2:4172 udp;

        proxy_pass vdi_pcoip;
        proxy_timeout 20m;
    }
